Document Type and Number:
Japanese Patent JP2017078612
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a measurement device with which the leveling work of a measurement device is efficiently executed.SOLUTION: The measurement device comprises a leveling unit 43, a measurement device body 44 provided in the leveling unit 43, a control unit 51, a first tilt angle measurement device 54 for detecting horizontality with high accuracy, and a second tilt angle measurement device 55 for detecting a wider range of tilt angles than the first tilt angle measurement device 54 and having higher responsiveness than the first tilt angle measurement device 54. The control unit 51, the first tilt angle measurement device 54, and the second tilt angle measurement device 55 are provided in the measurement device body 44. The control unit 51 drives the leveling unit 43 on the basis of the detection result of the second tilt angle measurement device 55, executes rough leveling until the tilt angle detected by the second tilt angle measurement device 55 falls within a range detectable by the first tilt angle measurement device 54, and levels up the measurement device body 44 on the basis of the detection result of the first tilt angle measurement device 54.SELECTED DRAWING: Figure 12
